Check out this Wii controller prototype from Bauhaus-University design student Martin Lihs. The spray paint can-styled casing contains a hacked up Wii controller that's used to manipulate virtual graffiti on a monitor. And since this is an art project, you can bet there are a wide variety of colors, spray caps, and tagging techniques built into the thing. Eventually, Lihs plans to integrate the device into a communal wall as part of his final thesis. It will be a sort of social media/public tagging spectacle that will enable users from around the globe to work on the same piece of art. Best of all, there are no Friend Codes. [Wii Sprayvia Core 77]
